In approach followed in Eq. (REF ), while the continuity on the EoS is well ensured, the continuity in the speed of sound at the transition density, due to its artificial character, is not. Therefore, in order to ensure the continuity and a smooth phase transition, we employ a method presented in Ref. [1]}. We proceeded with the matching of the EoSs on the transition density by considering that, above this value, the speed of sound is parametrized as follows (for more details see Ref. [1]})
\(\frac{v_{\rm s}}{c}=\left(a-c_1\exp \left[-\frac{(n-c_2)^2}{w^2} \right]\right)^{1/2}, \quad a\in [1/3,1]\)
